Sgt. Brown pulled over Kim Bauer and her boyfriend Miguel for speeding as they fled from Los Angeles. He decided to let them off with a warning, but noticed blood dripping from the rear of their vehicle. After he found the body of Carla Matheson in the trunk of the car, he called for backup and arrested them; Megan Matheson was separated from them in another cruiser. ("2:00pm-3:00pm")
Kim and Miguel revealed to Sgt. Brown and officer Collins that they were fleeing from a nuclear threat in LA, but Brown was unconvinced and later verified that there were no alerts among the various authorities. He did suspect that there may have been some truth in her claim when he was unable to get in contact with Frank Reed at the FBI. Brown later transferred Megan into the custody of her Aunt Emily, who lived in Santa Barbara, far from the danger zone. ("3:00pm-4:00pm", "4:00pm-5:00pm")
As Sgt. Brown brought Kim and Miguel to an SUV to escort them to downtown LA's central booking, Miguel resisted to cover up his retrieval of a cigarette lighter. On their way downtown, Brown radioed LA County 470 and spoke to Bill Gucoff. As he talked, Kim and Miguel started a fire inside the police vehicle, causing Officer Brown to lose control of the vehicle and swerve off the 118, crashing into the ground. After a time, Kim fled and left the two men in the SUV. ("5:00pm-6:00pm")
Though Sgt. Brown and Miguel were badly hurt, both survived the crash. ("1:00am-2:00am")
- Kim Bauer: I'm her au pair.
- Officer Brown: Her what?
- Miguel: She's her babysitter.
- Officer Brown: I wasn't asking you. ("Day 2: 2:00pm-3:00pm")
